Can you run a chain in production class motorcycle (Buell) if the bike originally came with a belt?
-
I can see why you would like to run a chain and have more gearing options but I'm sure others will chime in and agree, that the answer is no.

Scott gets it... :mrgreen:

Thanks for the info.

Sorry "Pops" just because my 240 open bike is legal this year does not mean it is legal next year.....right.. :evil:

Well, that would sure make it easier to "borrow" chain parts from you again :-D

Performance advantages by altering the oem design is not allowed in the production bike classes (without being ok'd by the race director or president that is).
A performance advantage by running a 520 series sprocket and chain setup where a 530 series setup was original equipment is not allowed in Production class. Changing from a belt to a chain (which of course has a simliair advantage to it) is not allowed either. Even running a very light weight drilled aluminum rear sprocket on your bike that came with a solid steel rear sprocket (even though it is the same size or series chain) will most likely get you protested by your competitors whether it makes it through inspection or not.
Only sprocket and pulley changes within their original configurations can be done. For instance, the number of teeth on the sprockets or pulley (IE: diameter of the chainwheels) can be modified to better accomodate the speed you are attempting.
The reasoning for wanting to change from a belt to a chain is obvious... and an alternative might be to investigate a combinatrion of other simliiar tire sizes within your speed ranges, pulleys that were made for the same bike in other countries, and primary drive or even transmission gear options.

Not a M/C guy but didn't the first Buells have a chain? HD Sportys had chains in '90, I put the first belt in SoCal on my '89 1200 in late '90 bought as a kit. As an observer I thought the rules for Production were as Scott stated..........rather use 4 wheels on the race track and 2 wheels getting there.. :-D

Interesting that the question is basically about a Buell. May I add a humble question/comment. Last year at the BUB meet a Buell XBRR which is a factory built formula racer ( I believe only 50 were made for certain teams), was allowed to run in a Modified /Production Pushrod class. Could that happen at ECTA ? The way I read the rules from both organizations, I would say no. as per ECTA -( This class does NOT include factory produced road racing or any other "works" racing models". Very similar to the BUB/AMA rule.- As per BUB - AMA (Overall construction of the modified frame must be based on the original "production" design and geometry and NOT PURPOSE built.) So where does the actual definition of "production" come into play? Everything is "produced", it doesn't just appear. To me, a production classed machine should be one thats mass produced and available to the general riding public. The XBRR was never mass produced for the general public consumption with only 50 made and sold to specific Formula dealer/teams, yet was allowed to compete in a M/PP 1350 class. Much to my objection I must add.
I'd love to have some feed back from Scott, Todd, John, and whoever has an opinion on this XBRR. Should it be allowed in "Production" classes when in reality it was a special purpose built Formula racing machine with only 50 manufactured.

At the ECTA an XBRR must run in the Altered class. Race specific bikes must run in Altered. We've had more then one race specific produced bike at our track an XBRR included. If we find them we stick them in Altered. People like you help us find them! ;)

deb---raining here--dont the ECTA and the SCTA have the same frame classes in motorcycle ---the SCTA doesnt have an altered motorcycle class there is an A class but it is special construction --- one more race and were done until may 09 --guess ill have to work to pass the time LOL willie buchta
-
Well, I'm not talking XBRR here, so it looks like I had better find a selection of belt drive sprockets or run Modified production.
BTW, thanks for all the responses.

JimmySix... Scott is correct although we did adopt the SCTA's practice of allowing changes in gearing (even the visible rear, against some of our objections) to allow the bike the physical ability of obtaining the required speed if it has the power and aero combo to do so.
Jim, excellent question especially since the ECTA doesn't allow the class combos the AMA does (IE: seperating frames and motors by production, modified, etc), but you are correct in your thinking for our venue in that a factory race bike has (or could have, which is up to it's oem of course) an advantage that other production motorcycles do not, and therefore is classified as an altered bike with us. As Deb stated (and has happened with multiple bikes at Maxton) it takes the other entrants on hand and even spectators to help police the rules sometimes as it's not always obvious to the the entrant in question that he or she is not conforming to the rules. And The Buell XBRR is a factory race bike and was properly placed in the altered class when last raced at the ECTA, and I (unfortunatley, at this point) know nothing about the AMA rules or classes.
Willie, altered and special construction are one in the same but you are correct in the newer and correct terminology being special construction.

Hey Thanks everyone. Todd I totally agree that the XBRR should be run in an Altered or Special Construction class. I think the AMA/BUB decision to let it run in the Modified frame / Production Pushrod eng. class may just change the concept of that class at their event. I don't think that machine is even given a VIN number, so it could never even be licensed for the street. I sure wish the main players in the Mcy. Land Speed Racing community could get their regs together since they are so close anyhow. Seems like the car rules are pretty cut and dry. Yet the little nuances of difference in the mcy regs creates problems when going from one venue to the other. I guess its, when in Rome, play as the Romans do. Thanks again for the input, I totally agree, Altered or Special Construction.
Ya'll stay happy & healthy :cheers:
